Abstract: A system is disclosed for ensuring a properly aligned position of a pod door within the opening in a pod shell upon location of the pod at a tool load port. The door positioning assembly according to the present invention includes a cam affixed to rotating latch hubs of a pod door latching assembly, and a cam follower mounted around each of the cams, which followers include arm portions that extend out toward an edge of the pod door. When the pod door and shell are separated, the arm portions are held in a retracted position completely contained within the footprint of the pod door. However, upon rejoining the pod door to the pod shell, mechanisms in the port door rotate the latch hub cams. Cam rotation causes translation of the arm portions of the cam followers so that the ends of the arm portions extend out beyond an edge of the pod door and against a surface of the pod shell. In their extended positions, the arm portions maintain a desired vertical positioning of the pod door within the pod shell opening.

Abstract: A multi-door enclosure for housing electrical equipment has a mechanical interlock device that interacts with a main primary door of the enclosure and the existing latch mechanisms of each of the remaining secondary doors to prevent such secondary doors from being opened unless the primary door is first opened. The interlock includes a lever arm that engages and is displaced by the primary door when closed.

Abstract: A nuclear power plant fuel transfer tube quick operating remote closure device (10) comprised of a reducing ring (20) and a cover assembly (60). The reducing ring (20) is bolted to the transfer tube housing flange (12). Rotation of a chuck key advances jaws on the cover assembly (60) which feed closure latches (78) into a groove (40) on the reducing ring (20). The upper surface (80) of each latch (78) has a bevelled surface (82) corresponding to a bevelled surface (42) of the groove (40). As the latches (78) engage the groove bevelled surface (42), the entire cover assembly (60) is uniformly drawn toward the reducing ring (20). Machined seal faces (13, 30, 44, 68) and O rings (36, 74) provide a fluid and air tight seal between the transfer tube housing flange (12) and the sealing ring (20) and between the cover assembly (60) and the sealing ring (20).

Abstract: An improved storage cabinet is provided which is particularly suitable for the safe storage of flammable materials. An embodiment of the cabinet includes two side-by-side doors which close toward each other. Each door is self-closing, being biased in a closed position by a spring. For convenience, each door can be retained in an open position by a chain. The chain includes a fusible link which melts in the presence of a dangerous level of heat, allowing the associated door to close. In order to protect the interior, the doors have overlapping edges. Accordingly, the cabinet has a closing synchronization mechanism which causes the dual doors to close in a predetermined order. Sequential closing is necessary to effect a proper overlapping of door edges, providing a heat shield. Furthermore, the doors are self-latching, as one door has an independent, three-point latching arrangement which engages the cabinet housing at the top and bottom as well as the first-closed door.

Abstract: An improved locking feature for a watertight hatch incorporates a positive break-open feature to facilitate opening when the hatch is jammed with ice and/or debris. A plurality of radially extending/retracting locking bars cooperate with closing cams such that, when the bars are extended, the hatch is drawn into tight engagement with a sealing gasket. When the locking bars are fully retracted, in order to release the hatch for opening, at least selected ones of the locking bars cooperate with opening cam means whereby full retraction of the bars forcibly displaces the hatch in an opening direction with a high mechanical advantage, initially breaking the hatch free of any restricting ice formation or packed debris. Thereafter, the hatch may be readily opened by being manually lifted in a conventional manner. The arrangement makes it entirely feasible to configure the hatch cover to be flush with its surroundings, so as to be useable in sidewalks, for example, where there may be heavy pedestrian traffic.

Abstract: A demountable tonneau cover for enclosing the open top of a pick-up truck cargo box comprises a relatively light-weight laminated panel which fits onto the open top of the cargo box to enclose the cargo space. Two pairs of spring-loaded pins are mounted on the interior of the cover along opposite sides for releasably latching the cover to the sides of the cargo box. These pins are inaccessible from the exterior of the cargo box when the cover is on the box. Cables extend from the spring-loaded pins through passages within the cover to pull handles which are also mounted on the interior of the cover adjacent the rear edge. The pins are normally biased to extended positions for fitting into holes in the sides of the cargo box and thereby latching the cover in place on the cargo box. When the pull handles are operated, the pins are retracted out of the holes thereby allowing the cover to be displaced from the position enclosing the cargo space.
